I have produced this site,
as someone who uses statistics in my experimental
work, but I am not a statistician. The site is
intended to provide a simple, straightforward guide
to the basics of experimental design and to some
of the common statistical tests.

There are several excellent sites on Statistical
methods. But I think that many undergraduates (and
graduate students) want only a user-friendly beginner's
guide - or a refresher course - that enables them
to use statistical tests with a minimum of fuss.
That's the aim of this site. It is by no means a
comprehensive guide, but it will get you started
and, if nothing more, it will help you to understand
the meaning of the symbols you see in scientific
papers.

You can use this site in 2 ways:

If you know the statistical test that you want,
then go straight to the index of tests (see below).
